Corporation not later than 120 days in advance of the meeting at which the
election is to be held; provided further, however, that in the event that less
than 130 days' notice or prior public disclosure of the date of the annual

later than the tenth day following the date on which such notice of the date of
the annual meeting was mailed or such public disclosure was made, whichever
first

                                      -4-

occurs. Each such notice shall set forth: (a) the name and address of the
shareholder who intends to make the nomination, and of the person or persons

record of stock of the Corporation entitled to vote at such meeting and
intends to appear in person or by proxy at the meeting to nominate the person
or persons specified in the notice; (c) a description of all arrangements or
understandings between the shareholder and each nominee and any other person
or persons (naming such person or persons) pursuant to which the nomination or
nominations are to be made by the shareholder; (d) such other information
regarding each nominee proposed by such shareholder as would be required to be
included in a proxy statement filed pursuant to the proxy rules of the
Securities and Exchange Commission, had the nominee been nominated by the
Board of Directors; and (e) the consent of each nominee to serve as a director
of the Corporation if so elected. If the Corporation receives notice from a
shareholder pursuant to this Article 7.1 and such notice, in the judgment of
the Board of Directors, fails to comply with the requirements set forth in
this Article 7.1 in any respect, then the Corporation shall notify the
shareholder of the deficiencies with such notice within ten days of the
Corporation's receipt of such notice. Commencing on the day of receipt of the
deficiency notification from the Corporation, the shareholder shall have ten
days to cure all deficiencies and provide the Corporation with notice which
conforms to the requirements of this Article 7.1.

          A shareholder shall be entitled to re-submit a notice as provided in
this Article 7.1 only once for each annual meeting of the shareholders.  Only
candidates who have been nominated in accordance with this Article 7.1 shall be
eligible for election by the shareholders as directors of the Corporation.

          -------------------------

          At any annual meeting or special meeting of shareholders, only such
business as is properly brought before the meeting in accordance with this
Article 7.2 may be transacted.  To be properly brought before any meeting, any
proposed business must be either (i) specified in the notice of the meeting (or
any supplement thereto) given by or at the direction of the Board of Directors,
(ii) otherwise properly brought before the meeting by or at the direction of the
Board of Directors, or (iii) if brought before the meeting by a shareholder,
then (x) the shareholder must have been a shareholder of record on the record
date for the determination of shareholders entitled to vote at the annual
meeting, and (y) only if written notice of such proposed business has been
received by the Secretary of the Corporation not later than 120 days in advance
of the meeting at which the business is proposed to be transacted; provided,
however, that in the event that less than 130 days' notice or prior public
disclosure of the date of the annual meeting is given, notice from the
shareholder to be timely must be received not later than the tenth day following
the date on which such notice of the date of the annual meeting was mailed or
such public disclosure was made, whichever first occurs.  There will be no
opportunity to cure any deficiencies within any notice given pursuant to this
Article 7.2.

thereon, voting together as a single class, shall be necessary to approve any
action for which shareholder approval is required under Subchapters B, C, D, E
and F of Chapter 19 (Fundamental Changes) of the BCL (the "Fundamental Change"),
and any successor provisions thereto; provided, however, that the additional

Change if such Fundamental Change is approved, recommended and submitted to the
shareholders for their consideration by the unanimous vote of the directors of
the Corporation then serving.

          ------------------------

          Any action required or permitted to be taken at a meeting of the
shareholders, or of a class of shareholders, may be taken without a meeting upon
the written consent of shareholders who would have been entitled to cast the
minimum number of votes that would be necessary to authorize the action at a
meeting at which all shareholders entitled to vote thereon were present and
voting.  The consents shall be filed with the secretary of the Corporation.  The
action shall become effective immediately upon its authorization, or at such
later time as shall be specified  in the said written consent, but prompt notice
of the action shall be given to those shareholders entitled to vote thereon who
have not consented thereto.

                 8.  Inapplicability of Certain Provisions.
                     -------------------------------------

provisions of Subchapters E, F, G and H of Chapter 25 (Registered Corporations)
of the BCL, and any successors thereto, shall not be applicable to the
Corporation.

          ------------------------------------------------

     A director of the Corporation shall not be personally liable for monetary
damages for any action taken, or any failure to take any action, unless the
director has breached or failed to perform the duties of his or her office under
Subchapter B of Chapter 17 of the BCL and such breach or failure to perform
constitutes self-dealing, willful misconduct or recklessness; provided, however,
that the foregoing provision shall not eliminate or limit (i) the responsibility
or liability of such director pursuant to any criminal statute, or (ii) the
liability of a director for the payment of taxes pursuant to local, state or
federal law. Any repeal, modification or adoption of any provision inconsistent
with Article 9.1 shall be prospective only, and neither the repeal or
modification of this provision nor the adoption of any provision inconsistent
with this provision shall adversely affect any limitation on the personal
liability of a director of the Corporation existing at the time of such repeal
or modification or the adoption of such inconsistent provision.

     9.2  Mandatory Indemnification of Directors and Executive Officers.
          -------------------------------------------------------------

          (a)  The Corporation shall indemnify and hold harmless to the full
extent not prohibited by law, as the same exists or may hereinafter be
amended, interpreted or implemented (but, in the case of any amendment, only
to the extent that such amendment permits the Corporation to provide broader
indemnification rights than the Corporation is permitted to provide prior to
such amendment), each person who was or is made a party or is threatened to be
made a party to or is otherwise involved in (as a witness or otherwise) any
threatened, pending or completed action, suit, or proceeding, whether civil,
criminal, administrative or investigative and whether or not by or in the
right of the Corporation or otherwise (hereinafter, a "proceeding"), by reason
of the fact that he or she, or a person of whom he or she is the heir,
executor or administrator, is or was a director or executive officer of the
Corporation or is or was serving at the request of the Corporation as a
director, officer or trustee of another corporation or of a partnership, joint
venture, trust or other enterprise (including without limitation service with
respect to employee benefit plans), or where the basis of such proceeding is
any alleged action or failure to take any action by such person while acting
in an official capacity as a director or executive officer of the Corporation,
or in any other capacity on behalf of the Corporation while such person is or
was serving as a director or executive officer of the Corporation, against all
expenses, liability and loss, including but not limited to attorneys' fees,
judgments, fines, excise taxes or penalties and amounts paid or to be paid in
settlement (whether with or without court approval), actually and reasonably
incurred or paid by such person in connection therewith.

          (b)  Notwithstanding the foregoing, except as provided in Article 9.3
below, the Corporation shall indemnify any such person seeking indemnification
in connection with a proceeding (or part thereof) initiated by such person
only if such proceeding (or part thereof) was authorized by the Board of
Directors of the Corporation.

          (c)  Subject to the limitation set forth above concerning proceedings
initiated by the person seeking indemnification, the right to indemnification
conferred in this Article 9.2 shall be a contract right and shall include the
right to be paid by the Corporation the expenses incurred in defending any
such proceeding (or part thereof) or in enforcing his or her rights under this
Article 9.2 in advance of the final disposition thereof promptly after receipt
by the Corporation of a request therefor stating in reasonable detail the
expenses incurred; provided, however, that to the extent required by law, the
payment of such expenses incurred by a director or executive officer of the
Corporation in advance of the final disposition of a proceeding shall be made
only upon receipt of an undertaking, by or on behalf of such person, to repay
all amounts so advanced if and to the extent it shall ultimately be determined
by a court that he or she is not entitled to be indemnified by the Corporation
under this Article 9.2 or otherwise.

          (d)  The right to indemnification and advancement of expenses
provided herein shall continue as to a person who has ceased to be a director
or executive officer of the Corporation or to serve in any of the other
capacities described herein, and shall inure to the benefit of the heirs,
executors and administrators of such person.

                                      -7-

     9.3  Payment of Indemnification.
          --------------------------

          If a claim for indemnification under Article 9.2 hereof is not paid in
full by the Corporation within thirty (30) days after a written claim therefor
has been received by the Corporation, the claimant may, at any time thereafter,
bring suit against the Corporation to recover the unpaid amount of the claim
and, if successful in whole or in part on the merits or otherwise in
establishing his or her right to indemnification or to the advancement of
expenses, the claimant shall be entitled to be paid also the expense of
prosecuting such claim.

     9.4  Non-Exclusivity of Rights.
          -------------------------

          The right to indemnification and the payment of expenses incurred in
defending a proceeding in advance of a final disposition conferred in Article
9.2 and the right to payment of expenses conferred in Article 9.3 shall not be
deemed exclusive of any other rights to which those seeking indemnification or
advancement of expenses hereunder may be entitled under any bylaw, agreement,
vote of shareholders, vote of directors or otherwise, both as to actions in his
or her official capacity and as to actions in any other capacity while holding
that office, the Corporation having the express authority to enter into such
agreements or arrangements as the Board of Directors deems appropriate for the
indemnification of and advancement of expenses to present or future directors
and officers as well as employees, representatives or agents of the Corporation
in connection with their status with or services to or on behalf of the
Corporation or any other corporation, partnership, joint venture, trust or other
enterprise, including any employee benefit plan, for which such person is
serving at the request of the Corporation.

     9.5  Funding.
          -------

          The Corporation may create a fund of any nature, which may, but need
not be, under the control of a trustee, or otherwise secure or insure in any
manner its indemnification obligations, including its obligation to advance
expenses, whether arising under or pursuant to this Article 9 or otherwise.

     9.6  Insurance.
          ---------

          The Corporation may purchase and maintain insurance on behalf of any
person who is or was a director or officer or representative of the Corporation,
or is or was serving at the request of the Corporation as a representative of
another corporation, partnership, joint venture, trust or other enterprise,
against any liability asserted against such person and incurred by such person
in any such capacity, or arising out of his or her status as such, whether or
not the Corporation has the power to indemnify such person against such
liability under the laws of Pennsylvania or any other state.

     9.7  Modification or Repeal.
          ----------------------

          Neither the modification, amendment, alteration or repeal of this
Article 9 or any of its provisions nor the adoption of any provision
inconsistent with this Article 9 or any of its provisions shall adversely affect
the rights of any person to indemnification and advancement of

                                      -8-
<PAGE>

expenses existing at the time of such modification, amendment, alteration or
repeal or the adoption of such inconsistent provision.

                           10.  Bylaw Amendments.
                                ----------------

     The Board of Directors may adopt, amend or repeal the Bylaws with respect
to those matters which under the BCL are not reserved exclusively to the
shareholders.  No Bylaw may be adopted, amended or repealed by the shareholders
unless, in addition to any other vote required by law, these Articles or
otherwise, such action is approved by the vote of holders of at least 66 2/3% of
the votes cast by shareholders eligible to vote thereon, voting together as a
single class; provided, however, that the additional affirmative vote required
by this Article shall not apply to any shareholder adoption, amendment or repeal
of any Bylaw provision if such action is approved, recommended and submitted to
the shareholders for their consideration by the unanimous vote of the directors
of the Corporation then serving.

                11.  Reservation of Right to Amend Articles.
                     --------------------------------------

     The Corporation reserves the right to amend, alter, change or repeal any
provision contained in these Articles in the manner now or hereafter prescribed
by law and these Articles, and all rights conferred upon shareholders herein are
granted subject to this reservation.
